A high-density felt shrinking machine

Abstract

The invention provides a high-density felt flat shrinking machine, comprising a rack, a motor, a transmission, a coupler, a driving chain wheel, a driven chain wheel, a chain, upper press shafts, lower press shafts, pressure springs, a steam water pipe and a control box; the motor is connected with the transmission and the coupler in sequence; the coupler is connected with the main chain wheel connected with the driven chain wheel by the chain; the lower press shafts are respectively arranged on the shafts of the driving chain wheel and the driven chain wheel; an upper press shaft is arranged above each lower press shaft in parallel; the pressure springs are arranged at two ends of each upper press shaft; the control box is connected with a steam water pipe and a gearbox; the upper press shafts, the pressure springs and the steam water pipe are all arranged above the rack; an air outlet is formed in the steam water pipe parallel with the press shafts. The upper press shafts, the lower press shafts and the pressure springs are adopted for controlling the friction of a felt in the flat shrinking process, multiple times of fat shrinking can be realized at one step, the flat shrinking effect is ensured, and the productivity is improved; the steam water pipe is parallel with the press shafts, so the felt can uniformly suck water content before flat shrinking, and the flat shrinking processing demands can be met.

Description

technical field [0001] The invention relates to the technical field of fabric shrinkage pre-treatment, in particular to a high-density felt shrinker. Background technique [0002] Since the high-density felt is made of wool through processing and bonding, it is elastic, compact, and has small pores, and has good water and oil absorption. When the felt is exposed to heat and humidity for the first time, it will shrink strongly, forming irreversible wrinkles and wrinkles, causing quality problems such as unstable elasticity, poor dimensional stability, and color difference. Then the shrinkage of the cloth surface is uniform, and it is not easy to produce wrinkles and wrinkles. Therefore, it is necessary to use a suitable shrinking machine for uniform shrinkage during the pretreatment of the felt blank. [0003] At present, the shrinking machines on the market mainly produce the pre-shrinking effect of the fabric by steaming the felt fabric. However, due to the strong elastic...

AI Technical Summary

Problems solved by technology

However, due to the strong water absorption of the felt, when it rubs against the upper / lower felt, it will bring moisture to the felt, reducing the pre-shrinking effect

At the same time, moisture will also reduce the friction between the felt and the felt, so that the invention patent cannot meet the flattening demand of felt with a higher density
